Abstract

A tailgate assembly includes a tailgate and a telescoping ramp movably coupled to the tailgate. The telescoping ramp is movable relative to the tailgate between a fully retracted position and a fully extended position. In the fully retracted position, the telescoping ramp is entirely disposed inside the tailgate. In the fully extended position, the telescoping ramp is at least partly disposed outside the tailgate.

First claim

The invention claimed is:

1. A tailgate assembly, comprising:
a tailgate;
a telescoping ramp movably coupled to the tailgate, wherein the telescoping ramp is movable relative to the tailgate between a fully retracted position and a fully extended position;
wherein, in the fully retracted position, the telescoping ramp is entirely disposed inside the tailgate; and
wherein, in the fully extended position, the telescoping ramp is at least partly disposed outside the tailgate;
a door movably coupled to the tailgate such that the door is movable relative to the tailgate between a closed position and an open position, wherein, when the door is in the open position, the telescoping ramp is accessible; and
a locking assembly coupled to the door, wherein the locking assembly is configured to lock the door relative to the tailgate in the closed position, the locking assembly includes a tab movably coupled to the door such that the tab is movable relative to the door between a locked position and an unlocked position.

2. A tailgate assembly, comprising:
a tailgate;
a telescoping ramp movably coupled to the tailgate, wherein the telescoping ramp is movable relative to the tailgate between a fully retracted position and a fully extended position;
wherein, in the fully retracted position, the telescoping ramp is entirely disposed inside the tailgate; and
wherein, in the fully extended position, the telescoping ramp is at least partly disposed outside the tailgate; and
a bump coupled to the tailgate and a ramp hook coupled to the telescoping ramp, wherein the ramp hook is configured to engage the bump when the telescoping ramp is outside the tailgate, the tailgate further includes a track to allow longitudinal movement of the telescoping ramp, the telescoping ramp is configured to be fully removed from the tailgate, and the ramp hook is configured to be mounted on the bump to couple the telescoping ramp to the tailgate.

3. The tailgate assembly of claim 2 , wherein the telescoping ramp includes a first telescoping segment, a second telescoping segment, and a third telescoping segment, the second telescoping segment is slidably coupled to the first telescoping segment, and the third telescoping segment is slidably coupled to the second telescoping segment.

4. The tailgate assembly of claim 3 , further comprising a guide rod coupled to the tailgate, wherein the telescoping ramp is movably coupled to the guide rod to allow the telescoping ramp to move relative to the tailgate along a lateral direction.

5. The tailgate assembly of claim 4 , wherein the second telescoping segment is movably coupled to the first telescoping segment to allow the second telescoping segment to move relative to the first telescoping segment along a longitudinal direction, and the longitudinal direction is perpendicular to the lateral direction.

6. The tailgate assembly of claim 5 , wherein the tailgate defines an inner tailgate cavity, the tailgate assembly further comprises a track disposed inside the inner tailgate cavity, and the track extends along the longitudinal direction.

7. The tailgate assembly of claim 6 , further comprising a guide roller coupled to the guide rod, wherein the guide roller is sized to be movably disposed in the track to allow the guide rod to move along the longitudinal direction, the telescoping ramp defines a rod-receiving opening partially receiving the guide rod, and the guide rod is slidably disposed in the rod-receiving opening to allow the telescoping ramp to move in a lateral direction.

8. The tailgate assembly of claim 2 , further comprising a door movably coupled to the tailgate such that the door is movable relative to the tailgate between a closed position and an open position, wherein, when the door is the open position, the telescoping ramp is accessible.

9. The tailgate assembly of claim 8 , wherein the door defines a slot, and the tailgate assembly further includes a ramp hook coupled to the telescoping ramp, and the ramp hook is sized to be received in the slot, the tailgate further includes a track to allow longitudinal movement of the telescoping ramp, the telescoping ramp is configured to be fully removed from the tailgate, and the slot is configured to receive the ramp hook to couple the telescoping ramp to the tailgate.

10. A vehicle, comprising:
a truck bed;
a tailgate assembly coupled to the truck bed, wherein the tailgate assembly includes:
a tailgate movably coupled to the truck bed;
a telescoping ramp movably coupled to the tailgate, wherein the telescoping ramp is movable relative to the tailgate between a fully retracted position and a fully extended position;
wherein, in the fully retracted position, the telescoping ramp is entirely disposed inside the tailgate; and
wherein, in the fully extended position, the telescoping ramp is at least partly disposed outside the tailgate; and

a laterally-extending track disposed at a rearmost point of the tailgate when the tailgate is in an open position, the telescoping ramp has at least one protrusion, the tailgate defines at least one protrusion opening extending longitudinally to allow the telescoping ramp to move along a longitudinal direction, and the laterally-extending track includes a retention block to limit the movement of the telescoping ramp along the longitudinal direction.

11. The vehicle of claim 10 , wherein the tailgate is pivotally coupled to the truck bed such that the tailgate is pivotable about a first pivot axis, and the vehicle further includes a hinge assembly coupled between the truck bed and the tailgate to allow the tailgate to pivot relative to the truck bed about a second pivot axis, and the second pivot axis is spaced apart from the first pivot axis along a longitudinal direction.

12. The vehicle of claim 11 , wherein the hinge assembly includes a bar coupled between the truck bed and the tailgate, a first pivot pin directly coupling the bar to the truck bed, and a second pivot pin directly coupling the bar to the tailgate.

13. The vehicle of claim 12 , wherein the hinge assembly further includes a catch directly coupled to the tailgate, and the catch defines an open cavity sized to receive the bar.

14. The vehicle of claim 13 , wherein the hinge assembly further includes a locking pin removably coupled to the catch and the bar.

15. The vehicle of claim 14 , wherein the catch defines a catch hole sized to receive the locking pin.

16. The vehicle of claim 15 , wherein the tailgate is movable along the longitudinal direction when the locking pin is decoupled from the catch and the bar.

17. The vehicle of claim 15 , wherein the tailgate is pivotable about the second pivot axis when the locking pin is decoupled from the catch and the bar.

18. The vehicle of claim 10 , wherein the telescoping ramp includes a first telescoping segment, a second telescoping segment, and a third telescoping segment, the second telescoping segment is slidably coupled to the first telescoping segment, the third telescoping segment is slidably coupled to the second telescoping segment, the tailgate assembly includes a guide rod coupled to the tailgate, the telescoping ramp is movably coupled to the guide rod to allow the telescoping ramp to move relative to the tailgate along a lateral direction, the first telescoping segment defines a rod-receiving opening, the rod-receiving opening receives the guide rod, the second telescoping segment is movably coupled to the first telescoping segment to allow the second telescoping segment to move relative to the first telescoping segment along a longit
